United Healthcare / prescriptions no longer covered

My husband and I have used United Healthcare through his employer for 30+ years. About 5 years ago, we moved, and my asthma got much worse. I was INUNDATED with information/mail about controlling my asthma. I am well controlled right now, but in December, received a letter advising that my inhalers would be costing $25 each, instead of the $5 each I currently pay. There was no additional information offered about what would be substituted (if anything). After an hour on the phone with the company, I was told NOT ONE INHALER would be covered at the $5 price. Imagine your drugs going up over night by over 500%. Keep in mind, not one, but TWO inhalers per month at 500 percent - and NOT ONE INHALER provided. So much for insurance. So much for preventive health care. So much for 'managing' a chronic illness.
